CAReDOOR-LOCKING DEVICE.

Application filed February 27, 1922. Serial No. 539,555.

To all whom t may conce/Vn.'

Be it known that I, LAMBERT J. TILLMAN, a citizen of the United Statesof America, residing at rIoledo, in the county of Lucas and State ofOhio have invented certain new n and useful Improvements inCar-Door-Locking Devices, of which the following is a specification.

My invention relates to new and useful improvements in car door lockingdevices and has for an object to provide a device which is exceedinglysimple in construction, efficient in operation and relatively cheap tomanufacture.

Another object of the present invention is to provide a locking devicefor freight car drop doors of any form, wherein an angle iron will besecured to the bottom of -the door and on the outer end of the angleiron will be a bracket which in turn will be supported by a link whichis pivotally mounted on the side of the car; the pivotal supportcomprising a bracket on which there is pivoted, also, a short lockingbar which, when turned in one direction will permit the link to be swungyoutwardly to release the door, and which, when swung into the op`posite direction will tightly hold the link in engagement with thebracket positioned on the angle iron, thus tightly hold-ing and lockingthe door in its closed position.

l'vVith these and other 'objects in view the invention consists incertain new and novel features and combination of parts as will behereinafter more fullyl described and pointed out in the claims.

Referring now to the several figures showing a preferred embodiment ofthe invention,

Fig. 1 is a view in elevation showing a fragmentary portion of a side ofa car and the looking device, the latter being shown supporting a doorin its closed position and Fig. 2 is a sectional view taken on line 2--2of Fig. 1 looking in the direction of the arrows.

At the Voutset it might be mentioned that l have shown a fragmentaryportion of a car and a door and only for the purpose of illustration, asthe locking device may be advantageously used on drop doors of any form.

Referring now more specifically to the drawings, a fragmentary portion 1of a side of a car is shown to which is riveted a substantially invertedT-shaped plate 2, the leg 3 having formed therein a bearing d while theupper end of the leg is riv ted as at 5 to the side of the car body,while the bottom bar 6 is riveted as at 7 and preferably through areinforcing plate 8 which is placed on the inner side of the car body.About midway 'of the bottom bar (i of the plate 2 isfOrmedtheoutstanding stud 9 which is drilled as at 10 for the reception of arivet or bolt 11, which, together with a washer 12 are designed to holda locking bar or arm 13 rotatable on the stud, this bar 13 beingprovided with a Central opening le which is only slightly larger thanthe diameter' of the stud so that although the bar may be rotated, itwill not swing freely or rotate unless manually manipulated. Near theouter end of this bar 13, and on its outer surface, are the oppositelypositioned lugs 15 which may be used by the operator as handles when itis desired to revolve or turn this bar to lock or unlock the device.

Swingingly mounted in the bearing d of the upper leg 3 of the plate 2 isthe link l@ which is placed in position behind the plate 2 when thelatter is attached to the side of the car, the width of the link and thelength of the locking bar 13 being such that when the locking bar is inposition as shown in Fig. 1 it will just straddle the side arms of thelink and of course prevent the same from swinging outwardly from the carbody, while, on the other hand, when turned to a vertical or uprightposition the link will be free to swing to permit the lowering yof thedoor.

In the embodiment shown in the drawings, there is a fragmentary portionl? of a door bottom to which is riveted the Z-bar 18 which in turn isriveted to an angle iron 19 designed to extend completely across thedoor and outwardlybeyond the free sides of the car. Upon the outer endof this angle iron 19 there is riveted a small bracket 20, while beneaththe same is riveted the small bracket 21 which is curved or cut-out atits outer end 22 so that the bottom bar of the link 16 will pass withinthis cut-out portion 22 when the door is in its supported position.

The door in the present embodiment also has the downturned iiange 24which will lie adjacent the lower strip 25 of the sideof the car body,while the upper bracket 2O will also lie adjacent the strip 25 but, ofcourse, on the outer side, the bracket and the door flange botlrprovidingya means-afer 'guidingi to both legs of the angle I9, asclearly shown` in Fig. 2. It will also be understoodY that any otherdesired form of bracket Yor brackets might be .usedlxW-hieltwillnprovidea ledge or engaging surface for the link.
